Back of '06 Harley F150 too High

[Ken2007HD]

...Maybe it is the tires with the lower profile side walls... The manual says to inflate them to inflate them to a max of41 pounds and no more inflation will help with the load carrying etc. It suggests 36 pounds for normal driving with the Pirrelli Scorpions. It's odd (or maybe normal!) that no one rally can come up with the definitive answer.

The Pirelli P275/45 VR22 tires are 'P' rated construction... intended for Passenger car use. Switching over to 'LT' rated tires would bring the load capacity back up to normal F-150 limits. 'LT' = Light Truck

Additionally, P construction tires are derated 10% when used in LT applications - Pickup trucks, Vans and SUV's. So what you see printed on the sidewall is not necessarily the actual load capacity.

Example:
OEM BFGoodrich LT275/65 TR18 on a 2007 F150 Lariat Super Crew 4wd are rated at 2601 lbs.

OEM Pirelli P275/45 VR22 on a 2007 F150 Harley Davidson Super Crew are rated at 2469 lbs.

But the P tires put in the LT application of the Harley F-150 effectively have only a 2222 lbs rating... lowering the Harleys' payload and towing capacity even further than what the sidewall says. Sorry for the hijack.
